Some recent problems

3. Complicated
Common elements with the
construction process employed
by other students
Movement from “incomplete”
personal conceptual maps to
scientific community conceptual
maps
Valid knowledge
Background
Educational Considerations
Education should be perceived as an individual construction that
leads to collective knowledge acceptable by the scientific
community:

4. Conceptual - Inscriptions
Maps
Learning - Transactions
Processes
Students - Nodes
Students’ Smart
Certificates - Contracts
Blockchain Technology in Education
A Metaphor

5. Blockchain Technology allows the
treatment of knowledge as constructed
by individuals through similar chunks of
knowledge (represented by blocks =
codes)
Problem: how can we deal with individual
constructions in a collective way?
The acquisition of new valid
combinations can be verified in an
independent, collective and generally
acceptable way
Towards a Liberating Pedagogy (1/2)

6. The identification of the subject of each misconception is
necessary
Blockchain technology renders this identification inessential and
thus individual learning in a collective mode can be achieved

7. Advantages of Blockchain
Technology (2/4)
Students
Reconstruction of cognitive
route
Comparison with other
students
Overcoming cognitive
obstacles
Teachers
Application of appropriate
learning techniques
Selection of proper learning
material
Sharing of data in a
transparent, secure and
efficient way
Transparency of successive
inscriptions: cognitive obstacles
are easy to be overcome
through effective pedagogical
ways

8. Immutable and secure
inscriptions
Detailed and accurate
certifications
Reduced cost of
verification
Eliminated risk of
fraud

9. Advantages of Blockchain
Technology (4/4)
Personalized learning:
the instructor is able to advise
students according to their
mistakes or manage mistakes
depending on students’ needs

12. Basic information (recipient,
issuer, date …) is stored in
a digital file:
This (credential) is
structured according to the
IMS open badges standard.
It is cryptographically
"signed" with a private key
(only the issuer has access),
and appended to the
credential itself.
